Abstract: Disclosed is an automatic specimen feeding system and a control method therefor. The automatic specimen feeding system includes a main frame installed adjacent to a carbon measuring apparatus, having a space with an open upper portion; a specimen seating unit which reciprocates horizontally in a direction perpendicular to the carbon measuring apparatus while moving up and down with respect to the main frame, and on which a plurality of specimens can be seated; a specimen lift unit which is installed under the specimen seating unit and can lift one of the plurality of specimens seated on the specimen seating unit; and a specimen input unit which is installed lengthways in the direction towards the carbon measuring apparatus to grip specimens lifted by the specimen lift unit and to input the specimens into the carbon measuring apparatus.

Abstract: A coupling device for a mask test means is disclosed. Provided according to an embodiment of the present invention is a coupling device for a mask test means, comprising: a pressing member which can receive a first member of a mask test means on one side thereof and can move up and down; and a support member which can receive a second member of the mask test means on one side thereof and is disposed below the pressing member, wherein the support member includes a lower member having a perforation means for forming a perforation in a mask, and the pressing member includes an upper member into which at least a portion of the perforation means can be inserted.

Abstract: The present invention relates to an automatic specimen feeding system and a control method therefor, the automatic specimen feeding system comprising: a main frame installed adjacent to a carbon measuring apparatus, having a space with an open upper portion, and being provided with an input hole for inputting a specimen into the carbon measuring apparatus; a specimen seating unit which reciprocates horizontally in a direction perpendicular to the carbon measuring apparatus while moving up and down with respect to the main frame, and on which a plurality of specimens can be seated; a specimen lift unit which is installed under the specimen seating unit and can lift one of the plurality of specimens seated on the specimen seating unit; and a specimen input unit which is installed lengthways in the direction towards the carbon measuring apparatus to grip specimens lifted by the specimen lift unit and to input the specimens into the carbon measuring apparatus.

Abstract: Disclosed is a filter cassette magazine and an apparatus for sequentially gathering fine particles using the same, in which a ‘filter cassette not having gathered fine particles yet,’ is received from a first magazine and the received filter cassette is transferred to a lower portion of an upper filter holder, the ‘filter cassette not having gather fine particles yet’ is pushed up toward the upper filter holder by lifting a lower filter holder so as to gather fine particles from outside, the ‘filter cassette having gathered fine particles’ is transferred to a lower portion of a second magazine, and the ‘filter cassette having gathered fine particles’ is pushed up and stored into the second magazine by lifting a push rod. Therefore, it is possible to implement simple maintenance and management, reduction in malfunction, and reduction in parts for machines and equipment.
